You have to locate the path /.well-known/acme-challenge in your filesystem. Then place a file “test” there and try to access it via http://w2.dbate.co/.well-known/acme-challenge/test. Unless this works, the location of this file in the filesystem is wrong and certbot won’t create the challenge files in the correct directory.
